Tool/software:

Hi there,
I am adapting the EtherCAT part of single_chip_servo example to my project, where EtherCAT runs on r5fss0-0.
We are using AM243x-LP board.

Because of conflicts of pins that will be used by motor sdk example, EEPROM is replaced with Flash.Basically I copied the changes from single_chip_servo example to our project.
In nvm_drv_flash.c: Flash_read() works, Flash_eraseBlk() works, Flash_write() triggers abort handler. HwiP_data_abort_handler_c (see picture).

How can I debug this flash issue?

Best,
Jinlong

Did you add Flash appropriately in SysConfig? You can try to make SysConfig and nvm related code similar to that in "motor_control_sdk\ind_comms_sdk\examples\industrial_comms\ethercat_slave_demo\device_profiles\402_cia" folder?

Regards

I did not spot any mistake. I guess where else in my project there may be some conflicts of pins or unregistered callbacks.

In line with this error message, I wish to generalize the question. How are the interrupts of main domain and mcu domain managed? I usually see vector table of these interrupt service routine. Where are the interrupt service routines? Do you have an example project? Besides, which library must I rebuild or can I rebuild to debug abort exception? See this document: https://www.avaq.com/files/uploads/datasheets/bb092ac3-7e38-4db2-b689-8c4ac47f6013.pdf

Best,

I end rebuild TI libraries to add a few lines to print the offending line.
I wish to close this thread and open a new thread since Flash_write() in ospi_v0.c is having some issue.
